To get the DVD credits go into the "Human World" and head for the 'Pixar' door. When on that press down and you will highlight the credits on one of the door runways.

Better though is the Paper Airplane Contest. On Disc 2 go in to the "Human World", then through the 'Pixar' door. Highlight the Monsters, Inc. Eye and then press left and you will be able to select the plane that is flying around.

After going through the 'Monsters Only' door press right to highlight the eye inside the M.

Watch the Tour in the 'Humans Only' section of Disc 2 (you can skip through it with your remote). At the end you will see a set of doors. Select the one on the top left to get access to a gallery of drawings showing various ideas for how to use the Atrium at the new Pixar studios. Select the one on the top right for a short clip of Sulley throwing Boo (in her monster outfit)like a bowling ball. Check out the other doors too.

Now, this Trailer is already in the main features of the 'Release' door of the 'Humans Only' area, but can also be accessed going through the 'Monsters Only' door (I assume this is an egg for the kids to find). Press the "Monsters, Inc." eye to the right of the Menu screen. You will get the "Charades" Trailer.
